Opposition foreign affairs spokesperson Simon Birmingham says the government's announcement of its intention to have an external administrator appointed across the CFMEU's east coast branches is the "weakest possible action" it could take.
"Bob Hawke had the guts to deregister the BLF, Anthony Albanese is simply pursuing a process of putting an administration in place," Senator Birmingham said on ABC's Afternoon Briefing program on Wednesday.
Senator Birmingham said the Coalition would support measures "necessary to shut down and shut out the thugs in the CFMEU."
When asked about a potential Donald Trump presidency, Senator Birmingham said it was crucial for Australia that the US government was committed to the alliance.
"I have full confidence that Donald Trump would continue that, as he did in his first term, and would be really strong in terms of his support for the alliance if there is to be a second term," he said.
"Secondly, what we need to see is that they [the US government] are playing a strong leading role in the world, uniting democratic nations where possible to stand against autocracies and be very strong in that regard."
Senator Birmingham said it was crucial that democratic nations engaged with whoever was in power in the US to "advocate for an approach that ensures Russian and Putin do not prevail" and continues to support Ukraine.
"How that conflict is resolved and how democratic nations stand against it will be interpreted by other autocracies and will frame many of the years to come and be crucial," he said.
"I welcome the fact that Ambassador Kevin Rudd is at the Republican National Convention, is meeting with officials there, and it is crucial that he ensures Australia is in the strongest position possible if there is to be another Trump administration."
